For the first time the level of relics of the high-mountain flora of the northwestern edge of the highlands of the Caucasus has been established. The Fisht-Oshten Massif and the Black Sea Chain have a uniquely high level of relics - 51.0% (617 species), with a predominance of Tertiary-relic species - Rt - 41.2% (498 species). The second largest representation is a group of Holocene relics - Rx - 7.3% (88 species), the minimum represented Pleistocene relics - Rg - 2.5% (31 species). The relic level of alpine species is one of the highest in the Caucasus and is 52.8% (338 species). Alpine species also have predominance of Pliocene relics - 46.7% (299 species), the number of glacial relics is 2.5% (16 species), the share of xerothermic relics - 3.6% (23 species). In the preservation of relic species revealed general trends, depending on the remoteness of local flora from the main diaspora on the Fisht-Oshten Massif and the modern area of the meadow belt. These trends persist in Tertiary relics, while other patterns are observed for glacial and Holocene relics. The number of glacial relics fades to the west, most clearly it can be seen in alpine species. The number of Holocene relics as much as possible on the edge areas (Fisht-Oshten Massif and Mt. Semashkho) and minimally on the central peaks of the Black Sea Chain, where the Holocene expansion of xerophyte plants was insignificant.

For the first time the level of endemism in high-mountain flora of north-west edge of uplands of the Caucasus was estimated. A uniquely high level of endemism in Fisht-Oshten Massif and Chernomorskaya (Black Sea) Chain was observed: 28.4% (342 species) with predominance of Caucasian (9.2%), Pan Caucasian (7.4%) and West-Caucasian (5.1%) endemics. Colchis and North Colchis endemics total take 5.8%, and together with local endemics riches the third position. The level of endemism of alpine species is one of the highest in the Caucasus and is 43.2% (276 species). The levels of endemism revealed general trends, depending on the remoteness of local flora from the main diaspora on the Fisht-Oshten massif and the current area of the meadow belt. These trends are visible for endemics of all ranks, with the exception of the West Caucasian endemic, whose number is higher in the eastern part of Black Sea Chain and is falling sharply to the west part.

The Caucasus is by no means a homogeneous region. It consists of a very high mountain-chain, the main parts of which reach to a height of over 5000 metres, with others of 1000–1600 metres. Forming an isthmus between two seas, the Asiatic Caspian and the Mediterranean Black Sea, it is open to both eastern and western influence. There is no distinct boundary between its northern part and the endless Eurasiatic grasslands, and in the south it is connected with the Armenian and Anatolian highlands. South of the mountain-chain the Caucasus has a Mediterranean climate: vines, rice and tea are cultivated and it is rich in metals. North of the mountain-range also the soil is very fertile, especially in the valley of the Kuban river. There, in the northeast corner of the Euxine, prehistoric culture flourished very early and reached a high level. I shall here give an outline sketch of its character, and especially of the so-called Kuban culture of the Early Bronze Age, which takes its name from the Kuban river. This river flows into the Black Sea, but its upper course lies in the high mountains not far from the Elbruz. It has many tributaries, especially on the left, the Caucasian, side. Among these the Laba, the Belaya and the Abin may be mentioned.

An overland route by which oriental merchandise and ideas were transmitted to the Ionian Greeks via the Anatolian plateau and the river valley routes of the west was long ago posited by Hogarth, and supported by Karo, Barnett and others, although there was little evidence from central Anatolia to confirm it. More recently this route was virtually discounted in favour of a sea route from N. Syria, especially Carchemish, through the port of Al Mina, to Greece and Etruria, via Cyprus, Rhodes and Crete, discussed by Sidney Smith, Humphrey Payne, Mrs. Maxwell-Hyslop and others, which is assumed to have been at its height in the earlier eighth century; and Barnett has also shown the importance of a third route, from Azerbaijan to Trebizond and west via the Black Sea, for which the main evidence, a tomb group from the Caucasus, is probably later seventh century.It is clear that the second of these three routes carried the bulk of Oriental trade to Greece and the west. Undoubtedly the most important Orientalizing influences on Greece, as shown by Payne, were those from the Cypro-Levantine cultural province, and there is ample evidence of the exchange of pottery, terracottas and ornamental bronzes of Cypriot and Phoenician production between the Syrian coast, Cyprus, Rhodes, Samos, Miletus, Chios, Delos and the west.

We studied for the first time luminescence characteristics of the some micromycetes, isolated from the bottom sediments of the Black sea from the 27 m depth. Luminescence parameters were registered at laboratory complex “Svet” using mechanical and chemical stimulations. Fungi cultures of genera Acremonium, Aspergillus, Penicillium were isolated on ChDA medium which served as control. Culture of Penicillium commune gave no light emission with any kind of stimulation. Culture of Acremonium sp. has shown luminescence in the blue – green field of spectrum. Using chemical stimulation by fresh water we registered signals with luminescence energy (to 3.24 ± 0.11)•108 quantum•cm2 and duration up to 4.42 s, which 3 times exceeded analogous magnitudes in a group, stimulated by sea water (p < 0.05). Under chemical stimulation by ethyl alcohol fungi culture luminescence was not observed. Culture of Aspergillus fumigatus possessed the most expressed properties of luminescence. Stimulation by fresh water culture emission with energy of (3.35 ± 0.11)•108 quantum•cm2 and duration up to 4.96 s. Action of ethyl alcohol to culture also stimulated signals, but intensity of light emission was 3–4 times lower than under mechanical stimulation. For sure the given studies will permit not only to evaluate contribution of marine fungi into general bioluminescence of the sea, but as well to determine places of accumulation of opportunistic species in the sea.

A new species of the genus Cimmerites Jeannel, 1928, C. maximovitchi sp. nov., is described from the Akhunskaya Cave and Labirintovaya Cave, both located in the Akhun Karst Massif on the Black Sea Coast of the West Caucasus (Krasnodar Territory, Russia). The new species is rather isolated within the genus Cimmerites and occupies an intermediate position between species related to C. kryzhanovskii Belousov, 1998 and species close to C. vagabundus Belousov, 1998. Though both C. maximovitchi sp. nov. and C. kryzhanovskii are still known only from caves, these species are quite similar in their life form to other members of the genus which are all true endogean species.

The concept of a new approach to environmental assessment is offered in the system of integrated management of the resource and environmental safety of the coastal area of the Black Sea. The studies of the season and daily changeability in the bioluminescence field in the Sevastopol coastal waters has been conducted. For the first time considerable differences in the bioluminescence field seasonal changes in the surface and deep water layers and the reasons conditioning this phenomenon have been shown, using a method of multidimensional statistical analysis. The bioluminescence field vertical profile change in the Black sea coastal waters in the autumn period at night has been studied. It has been shown that according to the character of bioluminescence parameters dynamics a water column can be divided into layers: upper (0 – 35 m) and deep water (36 – 60 m). It has been revealed that life rhythms of the plankton community are the main reason for the bioluminescence field intensity variability. It has been revealed that 14-hour periodicity of the bioluminescence field is related to the changes in light and its variations with 2,5…4,5 hours are conditioned by planktonts endogenous daily rhythms. And here biotic factors effect mostly periodicity of the bioluminescence field intensity increase and fall down at the dark time of the day. Abiotic factors are of less importance in circadian rhythmic of the bioluminescence field in the neritic zone.

A mathematical model describing the change in the Black Sea level depending on the Aegean Sea level changes is presented in the article. Calculations have shown that the level of the Black Sea has been repeating the course of the Aegean Sea level for the last at least 6,000 years. And the level of the Black Sea above the Aegean Sea level in the tens of centimeters for this period of time.

Phoretic mites use bark beetles for transportation to new, suitable habitats. Some phoretic mites act as predators and parasitoids of the bark beetles’ immature stages, especially egg and early larval stages, and are potential agents for the biological control of scolytine forest pests. Mites live very frequently in relationships with other invertebrates. Many are found in association with various species of bark beetles. Here, a total of 41 specimens of different bark beetles of the genus Ips (Ips acuminatus, Ips sexdentatus and Ips typographus) were studied for presence, species composition, and abundance of phoretic mites. The beetles were collected on dead wood and parts of tree bark of Pinus nigra, Pinus sylvestris and Picea abies in the Black Sea Mountains in Kastamonu and Artin Province of Turkey. A total of nine mite species were found, including Dendrolaelaps quadrisetus, Ereynetes sp., Histiostoma piceae, Paraleius cf. leontonychus, Pleuronectocelaeno barbara., Proctolaelaps hystricoides, Schizostethus simulatrix, Trichouropoda lamellosa and Uroobovellaipidis. All species are identified for the first time within Turkish fauna.
